The impulses that lead to the complex desires of adult life can be arranged under a few simple heads. Power, sex, and parenthood appear to me to be the source of most of the things that human beings do, apart from what is necessary for self-preservation. Of these three, power begins first and ends last. The child, since he has very little power, is dominated by the desire to have more. Indeed, a large proportion of his activities spring from this desire. His other dominant desire is vanity-the wish to be praised and the fear of being blamed or left out.
